Abstract

The construction industry has strong ties with other industries, and so construction company insolvency also has a strong influence on other industries. Prediction models addressing the insolvency of construction company have been well studied. Although factors contributing to insolvency must precede those of predictions of insolvency, studies on these contributing factors are limited. The purpose of this study is to analyze the influence of changes in the housing market on construction company insolvency by using the Vector Error Correction Model. Construction companies were divided into two groups, and the expected default frequency(EDF), which indicates insolvency of each company was measured through the KMV model. The results verified that 10 largest construction companies were in a better financial condition compared to relatively smaller construction companies. As a result of conducting impulse response analysis, the EDF of large companies was found to be more sensitive to housing market change than that of small- and medium-sized construction companies.

타 산업들과의 연계성이 강한 건설업체가 도산할 경우 타 산업시장의 경기악화를 초래할 수 있어, 시장 환경 변화에 따른 건설업체의 부실화 예측모형 연구가 중요하게 다뤄지고 있다. 하지만 건설업체 부실화 예측에 앞서 부실화에 기인하는 요소에 관한 연구가 선행되어야 함에도 불구하고 이와 같은 영향 변수들에 대한 연구가 부족한 실정이다. 이에 본 논문에서는 건설업체 포트폴리오의 큰 비중을 차지하는 주택시장 변화가 규모별 건설업체의 부실화에 미치는 영향을 벡터오차수정모형을 통해 분석하고자 한다. 이에 건설업체를 규모별로 2011년 시공능력평가순위 50위권 기업 중 상위 10개와 하위 10개로 구분하였으며, 각 업체의 부실화를 나타내는 예상부도확률을 KMV 모형을 통해 측정하였다. 주택시장의 변화를 대리하는 변수로 2001년부터 2010년까지의 주택매매가격지수, 주택전세가격지수, 전세매매가격비율을 활용하였다. KMV모형을 활용하여 규모별 건설업체의 예상부도확률을 산출한 결과 선험적으로 인지하고 있듯이 상위 10개의 대규모 건설업체들이 상대적으로 규모가 작은 건설업체에 비해 경영상태가 양호한 것을 확인 할 수 있었다. 또한 벡타오차수정모형을 구성, 충격반응분석을 수행한 결과 주택시장 경기변동에 따라 대규모 업체의 부실화 정도가 중소 건설업체에 비해 더 심각함을 확인할 수 있었다.
